What's it gonna take to get people to see their sinfulness? What's it gonna take to turn hearts back to God that have gone astray? In Amos 3-4 God begins to call Israel back to Himself. He wants them to own their sin and escape the judgment coming.
Again, it can be easy to say, "I know someone who needs to hear this." but the reality is that we always start with our own hearts. When God exposes our sin, then we confess it and turn to Him, not from Him.
